Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
Hey folks,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
Hi.
I am using S130 softdevice version.
Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.
When...
Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hi,
I would like to check battery level using the SAADC of the nrf52840.
Assuming the voltage is less than 3.6V, do I need to have a resistor between the battery and the...
HI,
I am new to IoS development with NRF.
I am having NRF52840 DK, IoS device. I want to implement USB HID device application (similar to pulse/Gluco meter ) on IOS. I...
Hi,
I am not able to compile the SDK example by using SES for ARM V3.52.
I got one error which shown below:
It pointed to the link ldr r0, =%4
Thanks

Hi,
I am using fatfs of nRF5_SDK_15.0.0_a53641a.
I am writing a program with keil.
I am currently doing SPI communication with BLENanov2(nRF52832) and SD card with...
Hi,
I am implementing the UART on NRF52840. TX works but the RX doesnot. While debugging, I noticed that STARTRX task register is not getting set due to which the RXDRDY...
Hi Sir
We'd want to do RX testing with DTM mode, however, the dtm example code looks can't report receive data or total packets counts,
So that, we don't know how to determine...
Hello,
I'm using the nrf15822 chip and am using the ble_app_uart example from nrf5_sdk_12.2.0.
I know softdevice will automatically generate random numbers through RNG...
I've been told due to PAN 58 it is not possible to use EASY DMA with nrf52832 without switching to the deprecated SPI driver. Is there a workaround that allows the use of...
Hello,
We are going start custom PCB design by using nRF52840 chip and SDK 15.0, but confused for use 3rd party nRF52840 modules or design complete custom PCB using componenets...
Hi,
Despite knowing a fair bit of the theory of wireless comms (mainly PHY and MAC), I'm brand new to actual hardware configuration/protocol development, so please be gentle...
As a master device with a whitelist there is a limitation on how many slave devices can be connected. If i am correct, other than whitelist there is no restriction to the...
Hi,
How do I receive data from host (computer) on my BLE device(Nordic board)? I want to use a simple open source HID API to send data to Nordic board and glow an led or...
Hello, we have finished all prototyping with BLE modile from Taiyu Tuden, this module: https://www.yuden.co.jp/wireless_module/document/datareport2/en/TY_BLE_EYSGJNZ_DataReport_V1_9_20180530E...
Good day, I am new to this forum so I am having some problems posting my question. Sorry for any inconveniences. I am having serious problems flashing my custom NRF5282 board...
